Patented July 31, 1945 umrso STATES PATENT OFFICE ROTARY PUMP R MOTORByron n. Alibaugh, Vallejo, Calif. Application August 21, 1941,SerialNO. 407,792 I This invention relates to a rotary machine 2 Claims.

adapted for use either as a rotary engine or pump, the object of theinvention being to provide a machine of this character wherein thehousing or casing thereof embodies outer and inner sections, rotatablewith respect to each other, and. means for causing a constant rotarypressure on the sections, to cause the sections of the housing to movewith respect to each other, thereby compensating for wear, as well asexpansion and contraction between the movable blades of the machine andcasing or housing in which the blades move.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fullydescribedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawings Figure 1 is a vertical sectional view'througha machine constructed in accordance with the invention.

Figure 2 is a section view taken on line 2-2 of Figure 1.

Figure 3 is an elevational viewillustrating the yieldable means forautomatically rotating one section of the housing with respect to theother section to move the sections toward each other.

Figure 4 is a sectional view taken on line 4-4 of Figure 2;

Figure 5 is a fragmental sectional view illustrating the packing meansbetween the movable sections of the housing.

Figure 6 is a iragmental sectionalwiew illustrating the inner end of oneof the slidin blades,

showing the spring for moving the blade outwardly.

Figure *1 is a plan view illustrating the spring a member used in movingthe blades outwardly.

Referring to the drawings in detail, the machine comprises hollowbearings 5 which are formed with internal threads to receive the pipesections 6, through which liquid passes, during the operation of themachine.

The hollow bearings are formed on the member 1 which is substantiallywide and formed eccentrically with respect to the bearings 5. In-

ciined ports 8 are formed in the member I, one of the ports 8- being incommunication with the bore 9, while the other port 8 is iiicommunication with the bore it. These bores 9 and I0 provide.continuations of the hollow bearings 5 the inner ends of the bores beingseparated by the partition II. The inclined ports 8 extend to theperiphery of the member I, one of the ports 8 being in communicationwith the inlet chamber 8 to the end that liquid passing into the inletchamber 8 must pass to the periphery of the member 1 between adjacentblades H.

The reference character l2 designates the stator which embodies a widecarrier disk, formed with a concentric opening to accommodate the member1, and around which the carrier disk operates.

The carrier disk i2 is formed with spaced radiating guideways l3 inwhich the blades M are slidably mounted. Each of these blades comprisesa pair of like members, the outer edges thereof being beveled inwardly,presenting substantially narrow surfaces at the outer edges thereof, tocontact with the housing of the device, to be hereinafter more fullydescribed.

Extending at oblique angles with respect to the periphery of the diski2, are exhaust ports 9' that establish communication between thechamber 8" and the space between the member housing, the head of the pinbeing embedded in an opening of the carrier disk. Thus it will be seenthat the housing and carrier disk will stay together.

Mounted in each guideway I3, is a bar l8 that has one of its endspositioned in an annular groove of the housing section It, the oppositeend of each bar being disposed in an annular groove, formed in the diskI9 that is mounted within the open end of the housing section it. Thisdisk I9 is provided with a packing ring 20 to seal the sections of thehousing and prevent leakage between the sections. The present inventionembodies more particularly the detail construction as shown by Figure 5of the drawings which insures against leakage between the sections, bycompensating for wear and expansion and contraction between the .housingand wide disk l2. The inner edge of the section It with the section iiof the housing, by means oi.

the yieldable ring 22 which is shown as positioned behind the packingring 2| to urge it outwardly.

The bars I 8, provide supports for the spring members 23 that areconnected to the bars at points intermediate the ends of the springmembers, the free ends of the spring members 23 engaging the blades it,normally urging them outwardly into engagement with the housing.

housing, together with the carrier disk, rotate around the member 1, andin order that a leak-proof connection between the member I .and carrierdisk I2 will-be, insured, the member I is formed with grooves, in whichthe rings 24 are mounted, the rings contacting with the carrier disk, asclearly shown by Figure 1 of the drawings.

The sections of the housing are so constructed,

Q that one section flts within the other section, and the sections areformed with cooperating,

threads, so that the sections may be screwed to- Bether.

Secured to the section It, are pins 25 that are provided with openingsfor the reception of one of the respective ends or the spring 26associated therewith. The opposite end of the spring will be extendedinto an opening of the pin 21 carried by section I 01' the housing. Itwill of course be understood that .these pins 25 and 21 are arranged inpredetermined spaced relation with respect to each other so that thepressure exerted by the springs 26, will be evenly dis-. tributedtoinsure the true operation of the springs to accomplish their purpose.

These springs 2' are constructed in such a way that they are placedunder tension, with the result that when wear occurs between the bladesand housing, the spring members will rotate the inner section withrespect to the outer section of the housing, moving the sections closertogether, thereby compensating for this wear.

It will further be seen that the device is rotated in a direction sothat the internal friction causes the sections II and I8 of the housingto move apart with the result that the springs 26 are placed undertension, with the result that a close flt between the stator and housingis insured at all times.

When the device is to be used as a pump, power is applied to the rotor,through the medium of a belt not shown, and which operates over thepulley 28, secured to the hub of the housing. As the rotor operates, theaction of the device will be to pump liquid through the pipes 6.

What is claimed is:

1. In a device 01' the class described, a stator, a rotor embodying asectional housing, said housing sections having cooperating threadswhereby the sections are moved towards or away from each other when thesections are rotated with respect to each other, pins extending from thehousing sections, curved spring arms having their ends connected to thepins and adapted to rotate the housing sections with respect to'each'other, moving the sections together.

2. In a device of the class described, a stator, a rotor embodying asectional housing, a threaded annular flange forming a part ofeach-section,- the flange of one section adapted to flt within theflange of the adjacent section, said'sections adapted to rotate withrespect to each other, a packing ring gasket disposed between the edgeof one of the flanges and the adjacent section, said packing ring gaskethaving a beveled suriace, the free edge 01! one of the flanges beingbeveled and adapted to engage the beveled surface of the gasket, springarms connected with the sections. and adapted to rotate the sectionstowards each other compressing said gasket and providing a fluid tightconnection between the sections.
